You have bit depth (the audio data is represented by 8-bits, 16-bits,
32-bits, etc., per sample).  Which may be unsigned or signed (the
numbers represent absolute values above zero, or above and below zero).
The choice doesn't make a great deal of sense for audio, which goes
above and below zero, by its very nature.

And you have a sample rate (the audio data may be sampled at a rate of
44.1 kHz, for example, like compact disc digital audio, where 44,100
times a second an audio sample is taken, or made, depending whether
you're talking about recording or replay, at whatever bit-depth your
working in).

Lossy formats, or even some non-lossy compressed formats, can specify a
bit rate, where the amount of compressed data representing your original
signal is limited to a bitrate (how many bits per second), by varying
the amount, or type, of compression.  Essentially, how much data will
you compress by, or throw away.
